To all whom it may concern: l

Be it known that LHUBERT WAGNER, a

vsubject of the King of Bavaria, .and a resident of Munich, Ungererstrasse 58,- Bavaria, Germany, have invented a certain neW and useful Improvement .in Means for Mounting .Stone Litho aphic Rollers;and i do hereby declare the olloivinr to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the acconipanyin drawing, and to letters of reference marke there-` on, Which form a part 'of this specification.

. My invention relates to improved means for mounting stone lithographie rollers one of the objects being to so mount the roller that While it is firmly supported and Xed on the shaft at its two ends it does not come into direct contact with the shaft passing through it, As compared With the ordinary manner of mounting such rollers, vthis arrangement possesses the advantage of securing a certain amount of elasticity between the shaft and the roller, in the bearing through the hollow part of the latter, thus preventing the bursting of same.

' Another a'dvanta e of my invention is the provision whereby t e roller may be removed and again easily replaced upon Ythe shaft Without the necessity of adjusting and centering the same. The roller being iirmly locked upon the sleeve, it is only necessary replace the sleeve upon the. shaft, lock the fie and the roller is ready for use. "lie drawing shows a longitudinal, sectionl lview of one form of the invention.

, In the foi-m of my invention selectedfor illustration herein o', is 'the roller and l) the shaft upon Which the saine is mounted. The shaft b is provided at or near one end with a collar or other convenient means` against which the .roller may be positioned and locked on the shaft. One or both ends of the shaft may be threaded and provided with nuts g, g, by which the roller may be firmly locked in position. Y

The sleeve or roller holder is adapted to l be slip ed on the shaft and maybe threaded at A one or oth ends to receive the locking members d, d. If referred, one of the locking members may e constructed integral with the sleeve t', or it may be a separate member but rmly secured lthereto and not adjustable. 'ihe sleeve t may be additionally sel Specification of Letters Patent.

cured against turning on the shaft by a key m or other convenient means. In the resent instance the locking members d and d are provided .with cone-shaped bearings to receive the ends of the roller, and this means serves to center and correctly position the roller While it is being locked on the shafti These cone shaped bearings, together with the ianges d2 at the outer edges of the loclrl ing members, provide broad bearin faces between which theroller may e curely locked.

lf it is desired to use a rollerniade up of segments the locking members may be provided with an inturned flange at the outer edgeLadapted to embrace the end of the roller and thus securelyT llock the segments in place vboth 'u on the shaft and also with reother. lf desired a packing member f may be introduced between the `ends of the roller and the locking members.

Then the roller is to be mounted one of the locking members is secured to the end of the sleeve, the roller is slipped over the sleeve and the other locking' member is then Ascrewed onto the opposite end ofthe sleeve not be necessary to adjust and center the roller, it being. only necessary to slip the sleeve on the shaft and lock it in position.

It is to be understood that nia-ny modifications of the abo've construction may be made Without departing from the spirit and scope of my invention.

Having thus described ,my invention, vclia't l claim as new and desire to secure bri' Letters Patentof the United States of America, is:

Al. A device, of the character described comprising a shaft, a detachable roller holder, adjustable locking means for securing said holder to the shaft, roller locking ineinbers provided with broad locking surfaces, and means to secure said members to fie roller holder.
